Power is defined as rate of work done which means it is work done in 1 second of time
Now it is given that we have a horse that will give power 745.7 W
So it will do work of 745.7 J in 1 second of time
now if we wish to find the work done by horse in 0.55 s
so we can say



So it will do total work of 410.14 J in 0.55 s of time

30km. 24 the first two hours and 6 the half hour
Here’s the answer, idk, it might be correct
The initial velocity is the speed and direction of the car at the beginning
of the event.
You just said that the car "starts at zero". You might mean that it starts at
"location zero". But then you go on to tell us its speed after 10 minutes,
so it sounds like the "zero" at which it starts is zero speed.
In that case, its initial velocity is zero.
